Remote Operation
Configuration 5
5-3
Configuration
The remote interface is configured using the local interface before the remote is
connected. The parameters needed varies with the interface used.
IEEE-488 Address, Protocol
RS-232 Baud Rate, Data Bits, Parity, Stop Bits
RS-485 Address, Baud Rate, Data Bits, Parity, Stop Bits
To configure the remote interface follow these steps:
1. The remote interface is configured from the Setup Remote Menu. From the Main
Menu (press Prev. until the Main Menu appears) press Menu [F6] ⎢Setup [F2]
⎢Remote [F4].
2. Use the knob to highlight the desired parameter.
3. Use the numeric keypad to enter the address. The ENTER key must be pressed to
change any parameter.
4. Repeat steps 2 and 3 to set all parameters needed.

SCPI Command Format
SCPI mnemonics have two forms: long and short. The short form is all in capital letters.
The long form is the entire mnemonic. Commands may use either the short form or the
entire long form. No other forms are accepted. SCPI ignores case: uppercase and
lowercase are equivalent.
A SCPI command is made by following the command tree as presented in the command
summary. Each level adds a mnemonic to the command separated by colons. Mnemonics
enclosed in square brackets are optional and may be omitted.
Some mnemonics are followed by an optional numeric suffix. If omitted, the suffix
defaults to 1.
Multiple commands may be placed in a single message separated by semicolons. Each
command starts at the same level of tree where the last command stopped unless the
command starts with a colon. The first command in a message and any commands
starting with a colon start of the root of the command tree. IEEE 488.2 commands may
occur between SCPI commands without affecting the tree level.
Command parameters are separated from the command name by one or more spaces.
Multiple parameters are separated by commas. SCPI accepts numeric parameters with
optional sign, decimal point, and exponent. OFF is equivalent to zero and ON is
equivalent to one. Floating point numbers are rounded to the nearest integer for
commands accepting integer values only.
A message is terminated by a Line Feed (hexadecimal 0A). Carriage Returns, Tabs, and
other control characters are ignored.
SCPI Response Format
Only commands ending in a question mark have responses. Multiple values from a single
command are separated by commas. Responses from different commands in the same
message are separated by semi-colons. The response message is terminated by a Line
Feed (hexadecimal 0A).
Integer responses are returned as one or more digits. Boolean values (ON and OFF values)
are always returned as numbers with zero for OFF and one for ON. Floating point values
are returned in the format “+d.ddddddddE+dd”.
